The Chtarbanova lab is interested in studying the molecular mechanisms and cellular pathways that underlie brain immune reactions and age-dependent changes of immunity using the fruit fly Drosophila as an experimental model.
Our research aims at understanding (i) the triggers and causes of inflammaging (low-grade chronic inflammation that accompanies aging), (ii) the consequences of elevated immune activation in the brain and (iii) how the brain responds to infectious injury in order to preserve neuronal integrity and function. Moreover, we are also looking to (iv) identify novel age-dependent factors of the innate immune response following infection with bacteria and viruses.
